Chinese chive is an important leafy vegetable, for which nitrogen is vital for growth, development and nutritional quality. In order to study the effects of improved hoagland nutrient solution with different nitrate (NO3-) to ammonium (NH4+) ratios (25:75, 50:50, 75:25 and 100:0) on the contents of chlorophyll and mineral elements (Ca, Fe, Zn, Cu, Mn, Mg and K) for three cultivars, Saisong, Pingjiu No.4 and Pingjiu No.8, under 14 mmol/L nitrogen. An experiment was conducted at experimental plots and lab of the school of horticulture and landscape architecture, henan institute of science and technology. The results showed that the chlorophyll a, chlorophyll b and total chlorophyll of the three cultivars were all reached a maximum value with NO3- and NH4+ ratio of 50:50. The eight mineral elements contents were higher for three cultivars at a NO3- and NH4+ ratios of 50:50 and 75:25. It could be concluded that the NO3- and NH4+ ratio of 50:50 effectively improved the chlorophyll contents and promoted accumulation of mineral elements in Chinese chive under hydroponic culture and was the optimal ratio.
Key words: Chlorophyll contents, Chinese chive (Allium tuberosum rottler), mineral nutrients, NO3- and NH4+ ratio, , , ,
